    And they've fired off and landed another.. like clockwork.

    Speaking of which, Alan MacDonald, the guy that refused to sign the OK to launch papers, and argued it was dangerous to allow Challenger to fly the day it exploded, has passed away.

    He did it as a joke to launch the boring company and just so everyone is clear... its a roofing torch in a pretty case which you can buy from any hardware store in the US. Not a flamethrower...

    as aokman said, it was to raise capital for the boring company.

    Regardless, I wouldn't want to be not flamethrowered by someone.

    Elon is obviously happy with the success of SN10 and had a party with their own fireworks!

    And the team have fired off and landed another.. 8 launches this year already.

    This time a new record 9th flight to space and back for a single Falcon 9 first-stage rocket.

    Static fire test scheduled for Wednesday, launch expected later in the week.

    It's still an open question what these tests might look like, they've been vague as hell about it. I think the most likely test step before stacking the thing for orbit is to send just a starship, with heat-shield, up for a full-thrust suborbital launch with maximum possible reentry velocity. But before they do that they're going to need to verify the new alloy and thinner stage walls on SN15+, so you'd imagine this is still at best a couple of months away.

    A serious time limitation on any kind of orbital launch attempt at present is they havent built the launch tower, and per elon they've no ability to stack starship on the booster without it. Historically it's taken even spacex a hell of a long time to get a launch tower built and debugged, be interesting to see how much they're able to fast track it. I havent seen a whole lot of serious tower construction going on in the nasaspacefight/bocachicagal footage yet

    What kind of total ΔV do they expect to get from a Starship with full tanks though, allowing for atmospheric drag etc. etc?
    I know the performance of those Raptors is impressive, but surely they'll need to fling it up on some kind of 1st stage boom-boom to get anywhere close to orbital re-entry speeds and still have the safety margins to land it again?

    Not arguing that this would be the obvious next step of course... chuck it up and see how hot it is when it comes straight back down again. Different kind of test to orbital reentry, but obviously still very useful.

    Can you tell I enjoy KSP?
    My application to NASA will be accepted any day now, I'm sure... :)

    Enough to get some heating happening, certainly. I mean elon's said with zero payload it's just barely capable of SSTO, and yet we can get sort of mach50 reentry from a non-orbital-capable sounding rocket. Or ICBMs, come to that. All you need to achieve on that kind of parabolic trajectory is maximum possible altitude.

    Of course it'd be nowhere near sufficient to test the heatshield at lunar return velocities, let alone martian return velocities, but it'd be enough for LEO and to iron out any kinks (like tiles falling off)
